To all whom it may concern:

Be it known that I, CHAnLEs HENRYATKINs, a citizen of the United States of America, and a resident of Springfield, in the county of Hampden and St ate of Massachusetts, have invented certain new and useful Improvements in Cloth-Take-Up Mechanism for Looms, of which the following is a full, clear, and exact description.

This invention relates to improvements in cloth takeup mechanism for looms, and more particularly pertains to a novel take-up motion for a loom especially constructed for weaving fine wire cloth, such as employed for the wet pulp web carrier in a Fourdrinier paper machine. The invention is not necessarily confined, however,.to a wire weaving loom.

Under an approved manner of weaving fine wire cloth, the lay has its battening strokes or blows up to the cloth line and as limited thereby, and at whatever position such line may happen to be,the beating-up movements of the lay being under the impulse of the more or less elastic force with the tendency of sometimes terminating not so far forward as at other times.

An object of this invention is to provide a take-up mechanism including variable speed. imparting means, with provisions for controlling such variable speed imparting means from, or by, the extents of beating up movements of the lay, so that the clothbeam will have its very slow and gradual rotations at such rate of speed as to maintain the cloth line at substantially the same place just back of the breast roll; and in the carrying out of this object, if the cloth line becomes abnormally rearward, the cloth-beam is automatically caused to have its turning or taking-up movement slightly accelerated, or if there is a tendency of the made cloth to be too far advanced toward the breast roll, the tendency is automatically induced in the take-up-beam for a slightly retarded motion.

And another object of the invention is to provide a take up mechanism suitable for looms of most common description and generally used, which is most satisfactory and desirable by reason of its simplicity and the inclusion therein of the means constructed A on approved mechanical principles.

speed driving means for said shaft, and means variably movably actuated by the lay according to the extents of the beating-up movements of the latter, and controlling said variable speed guiding means.

The invention may be otherwise stated to consist in combinations and arrangements of parts as hereinafter described and set forth in the claims.

The improved cloth take-up mechanism is illustrated in the accompanying drawings, in which,

Figure 1 is a plan view of sufficient of a loom to show the location thereon of the new mechanism in connection with the parts of the loom with which it intimately coacts. Fig. 2 is a one side view of the loom showing the cloth-beam take-up mechanism as seen in elevation thereon. Fig. 3 is an elevation as seen from the opposite side of the loom. Fig. i is substantially a vertical sectional view, on a larger scale,through an important part of the novel mechanism hereinafter par ticularly referred to. Fig. 5 is a cross sectional view as taken on the line 55 on both Figs. 2 and 4. The section line 4-4, on Fig. 5, indicates the plane on which the section Fig. 4 is taken.

The drawings, Figs. 1, 2, and 3, show a warp let-off motion invented by me, and forming the subject of a separate application for Letters Patent of the United States filed of even date herewith, and not herein particularly referred to.

Similar characters of reference indicate corresponding parts in all of the views.

In the drawings,-A represents the loom frame of which a a are the loom sides.

B indicates the warp beam, C the cloth beam, D the breast roll, E the lay, and m indicates the warp wires with the shed converging to the cloth line just to the rear of the breast roll indicated in the side views at the oint y.

The cloth-beam C has a worm wheel F affixed thereon, and adjacent the edge'of said worm wheel F is a suitably journaled, and supported, axially vertical, shaft G having a worm H affixed thereon and in mesh with the cloth-beam worm-wheel F. The said shaft G has a portion formed screw-threaded, as indicated at I), such threads being of ratchet shape in the present instance.

So far as the present invention is con cerned, J may be regarded as the primary driving shaft, the same being by bevel gearing connected with the vertical shaft K having an upwardly tapering cone pulley L thereon. Parallel and suitably separated from the shaft K is another vertical shaft M having aliixed thereon a cone pulley N, the taper of which is downward; and the said shaft M has a worm d affixed thereon which is in mesh with the worm wheel 6 on the short horizontal shaft f, which by bevel gearing g, 9 is in drivin connection with the aforementioned shaft (Jr on which are the worm H and the threaded portion 6. A belt 0 runs around and between the reversely tapered cone pulleys L and M; and P represents a shifter for said belt, the same being pivotally hung at h 011 a suitable bracket therefor.

It will be apparent that if. the belt P is moved upwardly relatively to the widening portion of the cone pulley N, and the narrow portion of the pulley L, a retardation in the driving speed of the cloth beam rotating connections will result, the reverse being true when the belt is shifted downwardly relatively to the said cone pulleys.

Q represents a sleeve like nut carrier slidable vertically relatively to the threaded portion of said shaft G, and one or more nut sections i i are provided to, and su ported by, the said carrier and have detacha le engagements with the ratchet shaped threads of the said shaft G.

The nut sections, as shown, are made in the form of levers intermediately pivoted at j j to the sleeve like nut carrier within opposite vertical recesses therein; and these nut sections are by the springs 7r forced so that their toothed or thread engaging members i will be kept in engagement with the threads I) of the said shaft G whereby the rotation of such shaft will cause a downward feeding of the nut engaged part Q.

R represents a rod between and connected with the upper end of the nut carrier Q and an intermediate part of the belt shifter P and as indicated by the screw threaded formations m m, engaged in sockets in the connection sections n n, this rod is in substance longitudinally distensible and contractible whereby may be adjusted, for proper working of the mechanism, the relations between the nut carrier and the belt shifter.

S, S represent a two membered lever mounted at the side of the loom, the member S being'inwardly offset from the member S the one beinginside of the loom frame while the other is at the exterior thereof, the parts being united by the integrally or rigidly aflixed pivoted stud 07 The member S is formed with an upwardly inclined forward portion 10 normally in the path. of, and to be impinged against by, a projection or roller g on the side of the lay,-

' the same being carried, for instance, on a depending extension of one of the lay swords.

The other arm S of the said two membered lever is bifurcated to straddle an intermediate portion of the nut carrier Q, and has approaching studs rwhich engage in the opposite side recesses in the nut carrier.

The lay moving forwardly engages the lever S, S and swings the same more or less accordingly as the extent of the swing of the lay is excessive, or of scant extent. if cloth has been well taken up and the beating up .point is pretty well forward, the lay, in coming to the comparatively considerably forward point will swing the lever considerably and thereby considerably raise the nut carrier, the nut and the belt shifter, placing the belt on the larger portion of the tapered pulley N, and the nut on a higher screw threaded portion of the shaft and the screw and worm will be slightly retarded in their movements, with corresponding effect on the very slow taking up rotative movement of the clothbeam.

The screw I) constantly feeds the nut, and its carrier, in a downward direction, and moves the belt shifter in a downward direction, thus automatically insuring a running at a slightly increasing speed of the feed mechanism for the cloth-beam, but as above explained, whenever such feeding or taking up of the cloth beam becomes too much advanced, the action by the lay on the swinging lever, and through it on the nut, nut carrier, and belt shifter, is such as to insure a retardation in the driving of the cloth takeup mechanism.

The motion imparting mechanism for the cloth-beam is sufliciently duplicated so that the cloth-beam has rotative winding-up movements positively and concurrently imparted thereto at both ends of the beam, it being perceived that the shaft M is at its upper end, by bevel gearing 1), connected with a iorizontal transverse shaft T, which in turn by bevel gearing o drives a shaft M at the opposite side of the loom, which shaft has a worm (Z meshing into the worm wheel 0 on short shaft f and which by bevel gearing 9 drives a short vertical shaft Gr having a worm H which is in mesh with the worm wheel C on the other end of the take-up beam, it being, of course, apparent that no necessity exists for a duplication of the lever S S the nut carrier and nut, screw threaded shaft portion 6, belt shifter and cone pulley drive.
